An aircraft comprises a body 1 having wings 2, 3, propulsion means for producing a resultant propulsive thrust which acts through the centre of gravity 4, control means for adjusting the direction in which the propulsion thrust acts, and storage means 14, 15 for the fuel, the wings being capable of supporting the aircraft at cruising speed flight at sea-level when the storage means is empty but not when the aircraft is at its all-up weight. A gas-turbine engine 8 drives an axial-flow compressor 9 from which part of the compressed air enters engine 8 and the remainder is discharged through nozzles 12, 13. The exhaust gases from engine 8 are discharged through nozzles 10, 11. A lever 50. controls the supply of compressed air to the servo motor 33 which, by means of gear boxes 34, 35, 44 drive shafts 32a, 32b, and sprocket and chain drives, rotates the nozzles 10 to 13 in unison, the thrust of these nozzles being controlled by a control 52 on lever 50. Roll control is effected by lateral movement of control column 61 which operates valve 67 to control the supply of compressed air through pipes 18, 19 to nozzles 17a, 17b mounted on the wing tips. Nozzles 20, 21 pivotally mounted at the nose and tail are supplied through pipes 55, 57 and 58 with compressed air, the supply of which is controlled by a valve 56 itself controlled by fore-and-aft movement of control column 61 to effect pitch control of the aircraft.

Abstract: 786,889. Fluid-pressure brakes. NATIONAL SUPPLY CO., and OIL WELL ENGINEERING CO., Ltd. Sept. 16, 1954 [March 15, 1954], No. 26851/54. Class 103 (1). [Also in Group XXIX] A power booster providing " feel " for an operator and applicable to the control of a brake band 11 comprises a pair of interconnected levers 12, 13 of which the latter is connected at 23 to the brake band, at 24 to a spring-loaded power piston 54, and at its lower end to the body of a control valve 15. The lever 12 is pivoted at 20 to a fixed point and has a short arm pivoted at 22 to the lever 13 and a long arm having an hydraulic connection 19, 18, 17 with a manually-operated lever 16. Operation of the lever 12 causes movement of a member 39 which carries a seating for one element 43 of a dumbbell valve member 43, 44. When the lower end of the lever 12 is moved to the right pressurefluid can escape from a chamber 50 past the element 43 to an exhaust 57 thereby allowing.the piston 54 to be moved by its loading spring 10 to the right to increase the tensioning of the brake band 11 until the original spacing of the levers 12, 13 is restored. Movement of the lever 12 in the opposite direction causes pressure fluid to be admitted from a conduit 48 to the chamber 50 to cause the piston 54 to release the tensioning of the brake band 11. Operation of a valve assembly 58, 65 simultaneously cuts off the supply of pressure fluid to the conduit 48 and vents the chamber 50. In a modification pressure fluid acting on the piston applies the brake instead of releasing it whilst in a further modification the valve housing 15 is mounted on a fixture and the movable member 39 is connected to the lever 12 through a further lever which is pivotally mounted on the lever 13.

In a combined master cylinder and servomotor a part at least of the master cylinder is housed within a chamber in the forward end of the servomotor which is sealed-off from the power chambers. As shown, the casing 11 of the servomotor has a front wall portion 13 to which is secured an inwardly-projecting barrel 12 within which the rear end of the master cylinder 10 is received. A sleeve 15 slides on the barrel by means of a seal 16 and is in turn secured to a hub member 24 which slides in the rear part of the casing. The piston 30 of the master cylinder extends rearwardly in the chamber enclosed by this assembly and is connected by a pushrod 27 to a resilient button 40 seated in the forward end of the hub member, so sealing the chamber from the valve structure which is located within the hub member. The servomotor is of the vacuum suspended type having two diaphragms 17, 18 and a dividing wall forming two vacuum chambers 20, 21 and two power chambers 34, 35. The diaphragms are supported by respective plates 32, 33 secured to the sleeve 15 in association with a surrounding sleeve 19 which forms an annular space 22 for communication between the two vacuum chambers 20, 21. The power chambers 34, 35 communicate with one another by a peripheral passage 37. The valve assembly is located in the sliding hub member 24 so as to provide follow-up of the operating pedal which is connected to an operating rod 25. The rod 25 acts on a valve member 28 normally contacting an annular diaphragm valve 42 to maintain the latter off a seat 45 of the hub member whereby vacuum is communicated to the power chambers via radial passages 44 in the hub member. On depression of the pedal rod 25 urges valve member 28 forwardly until the diaphragm valve 42 engages the seat 45 under the influence of springs 49, 50, closing off the vacuum connection to the power chambers. Further movement of valve member 28 cracks the valve 42 to admit atmospheric air via a filter 39 and inlet chamber 23 to the power chambers 34, 35. Feel is provided by the resilient button 40 which when compressed due to the force exerted on piston 30 extrudes into the interior of the hub member to urge the valve member 28 rearwardly.
